# A JavaScript error occurred

* If you get an error like screenshot below when starting butler, please reset token bidding jobs manually before starting again: Please delete `redis-dump.rdb` in `C:\Users\<Username>\AppData\Roaming\NFTbutler`
* Then restart your computer and start Butler again Reason for this error: If Butler is closed while storing the latest Job information on your harddisc, the dump can be corrupted which gives Butler a hard time loading it again when starting.\ <br>
